I am getting heat in the car.
When I removed the thermostat housing, there was no antifreeze in the block or upper radiator hose.
I didn't mean to jump on you..... I work in the service industry (not automobile of course) and I know that in ALL areas of service, that you don't have to look HARD to find the good ones of anything. People in the service industry rely on repeat customers and referrals so they are not going to take advantage of people the majority of the time. There are bad 'ones' in every industry, but those are the MINORITY.
Anyway, I had the exact same scenario as you.
Except I first had a leaking water pump on my 03 T&C. I had it replaced and I noticed my upper hose still didn't have pressure. With the cap off, I could never really see movement of the coolant. And I had to put more coolant in periodically. Not very often, but enough that I would need to check it every few days to be sure. Even when the coolant level got a gallon or more low, my temp gauge would not go higher than half way.
I finally found it. Just simply a hole in the radiator. But the water didn't spew out... the leak was so slow and small it just followed along the fins of the radiator and I never saw it actually drip to the ground. There were no tell-tell signs such as water vaporizing or a coolant smell. I'm still amazed at how there was no pressure at all on the hose with such a tiny leak.
New radiator on and as soon as the engine warmed up I had pressure on the upper hose finally. With the old radiator off and in good light I could see the discoloration of where the coolant was coming out. It was on the INSIDE of the radiator too which was more odd as it wasn't caused by something hitting it from driving down the road.
Just look very carefully with a flash light all over the radiator.
And hopefully you don't have a coolant smell inside the van? If so that would be the heater core but you should be able to smell that most of the time.
